The tension so applied to the ring, gives the ring a firm grip on the boss or platform 1.' This arrangement permits ready attachment and detachment of the combined wick and bottle support II] on the-cup. Likewise, when the support It) is detached from the cup, wicks may readily be detached from or applied over same by causing the split ring 9 to pass through the hollow center of the wick. In normal operation, the mouth of the inverted bottle is beneath the upper edge of cup 5, thus providing for discharge of fluid from the bottle, controlled by the fluid level in the cup 5. r

The lugs or legs 8 prevent formation of a Vacuum between the base 2 and cup 5 which might prevent ready separation of the cup from the base 2.

From the above description of my improved air purifier, it will be apparent that I have provided a device which has improved diffusion capacity and which also may be readily assembled and disassembled.

- The foregoing detailed description has been given for clearnessof understanding only and no unnecessary limitation should be understood therefrom, but it shouldbe construed as broadly as permissible in view of the prior art.

What is claimed is:. g

1. An air purifier of the kind described herein comprising an apertured container having a base portion and a hinged cap, a removable wick base cup adapted to rest upon the interior of the container base, said base cup having upwardly extending edges, and a circular elevated platform upon its upper surface and depending legs upon its lower surface, a split ring prong holder embracing said circular elevated platform and in frictional engagement therewith. said prong holder having a plurality of upwardly extending prongs for the reception of a wick thereon and to support the shoulders of an inverted bottle, a

' wick surrounding said prongs and extending into said base cup, an inverted bottle containing fluid within said container and supported upon said prongs, said bottle having a neck containing a valve and a release pin adapted to permit the flow of liquid through said bottle neck and into said base cup and wick.

2. An air purifier comprising a container having apertured side walls, a base, and an aper-' tured hinged cap on the top of said container, a

removable Wick base cup adapted to rest upon the interior of the container base, said basecup having upwardly extending edges, and a circular elevated platform upon its upper surface and depending legs on its lower surface, a ring prong holder embracing said circular elevated platform and in frictional engagement therewith,

said prong holder having a plurality of upwardly extending and outwardly bent prongs for the reception of a wick thereon and to support the shoulders of an inverted bottle, a wick interwoven with said prongs and extending into said base cup, and an inverted bottle containing fluid within saidcontainer and supported upon said prongs,

and means on the neck of said bottle for con-' trolling the passage of fluid therethrough.

3. A removable wick base and holder comprising a cup having upwardly extending edges, a circular elevated platform, said platform having in frictional engagement therewith a split ring prong holder having a plurality of upwardly extending prongs attached thereto. a

4. A removable Wick base and holder comprising a cup having upwardly extending edge portions, a circular elevated platform on the upper surface of said cup, a split ring prong holder embracing said platform and in frictional engagement therewith, said prong holder having a plu-' rality of upwardly extending prongs. attached thereto, and a wick. of woven material extending over said prongs and into said cup." 5. In a device of the class described the combination of a foraminous housing, a non-metallic rigid cup supported in said housing, the cup having an upwardly extending boss formed on its bottom wall, a spring metal ring frictionally receiving and extending about said boss, a plurality of spaced supporting members carried by the ring, an annular wick supported in extended position by said supporting members, with the lower end of said wick disposed within said cup,

and a supply reservoir open at its lower end only,

disposed upon and supported by the upper portions of said supporting members, with the opening therein positioned in the cup and belowthe upper edge of the cup.
